A church treasurer has been found guilty of murdering his 48-year-old wife by deliberately steering their pick-up truck off a motorway at up to 84mph.

Ian Walters claimed to remember nothing of the 130-mile (209km) journey leading up to the crash on the M1, which saw his Mitsubishi L200 "implode" on an embankment near Markfield.

But text messages sent by his wife Tracy proved that the 51-year-old was "driving and volatile" as the couple returned home from a make-or-break week away at a cottage in North Yorkshire.

A six-week trial at Leicester Crown Court also heard that Walters, a church treasurer and driving test examiner from Swindon, was questioned over claims of domestic abuse a week before the murder on March 21 last year.
